Researchers in the United States say they have created an ultra-slippery toilet that can help save huge amounts of water around the world.
Scientists at Penn State University say that coverage reduces the amount of water needed to flush excrement by 90%.
They say that it also prevents the accumulation of bacteria in toilet dishes and reduces associated odors.
Spray, ie. which is more slippery than Teflon, would be affected by urine and need to be re-administered after about 50 ppm.
Researchers hope the discovery can help reduce water waste. Every day, more than 1
- Water bill "too expensive" for flushing the toilet
- Public toilets "an absolute necessity", politicians warned
According to researchers who published their findings in the journal Nature Sustainability, fresh water used to wash the world toilets are six times greater than total water consumption in Africa every day.
"Our team has developed a healthy bio-inspired, liquid, sludge and bacterial repellent layer that can essentially make the toilet self-cleaning," Tak-Sing Wong, an associate professor of mechanical engineering at the university, told Penn State News.
"Toileting from toilet to toilet is not only unpleasant for consumers, but also poses serious health concerns," he said. "Our goal is to bring impactful technology to the market for everyone to benefit from," he added.
